PURPOSE To study the efficacy and safety of deep sclerectomy with collagen implant in one eye versus trabeculectomy in the other eye of the same patient. METHODS The authors conducted a nonrandomized prospective trial of 20 patients with medically uncontrolled primary and secondary open-angle glaucoma. Patients with bilateral medically uncontrolled(More)
PURPOSE To evaluate the long-term success rate and complications of nonpenetrating deep sclerectomy with collagen implant in open-angle glaucoma. PATIENTS AND METHODS Clinical, prospective, monocentric, nonrandomized, unmasked study on 105 patients with medically uncontrolled glaucoma. A standard procedure deep sclerectomy with collagen implant was(More)
PURPOSE To study prospectively the success rate and complications of deep sclerectomy with collagen implant (DSCI). SETTING Glaucoma Unit, Department of Ophthalmology, Hôpital Ophtalmique Jules Gonin, University of Lausanne, Lausanne, Switzerland. METHODS This nonrandomized prospective trial comprised 105 eyes of 105 patients with medically uncontrolled(More)
AIM To identify the value of using collagen implant in deep sclerectomy. METHODS A prospective randomised trial of 104 eyes (104 patients) with medically uncontrolled primary and secondary open angle glaucoma. All patients had deep sclerectomy (DS), half of them with and the other half without a collagen implant (CI) sutured in the scleral bed. The main(More)
Nonpenetrating glaucoma surgeries have been developed in recent years in order to improve the safety of conventional filtering procedures. The goal of nonpenetrating filtering procedures is to reduce intraocular pressure by enhancing the natural aqueous outflow channels, while reducing outflow resistance located in the inner wall of the Schlemm's canal and(More)
AIM To study the possibility of using intraocular pressure (IOP) in the first postoperative day after sclerectomy as a prognostic indicator. METHODS Non-randomised prospective trial involving 105 eyes of 105 patients with medically uncontrolled primary and secondary open angle glaucoma. Visual acuity, IOP, and slit lamp examinations were performed before(More)
AIM The use of an animal model to study the aqueous dynamic and the histological findings after deep sclerectomy with (DSCI) and without collagen implant. METHODS Deep sclerectomy was performed on rabbits' eyes. Eyes were randomly assigned to receive collagen implants. Measurements of intraocular pressure (IOP) and aqueous outflow facility using the(More)
The evidence in support of intraocular pressure (IOP) lowering to reduce risk of glaucoma onset or progression is strong, although the amount and quality of IOP reduction is less well defined. The concept of a target IOP includes a percentage reduction, calculated IOP, or a predetermined IOP figure or range. Yet none of these strategies have been validated.(More)
PURPOSE To evaluate the safety and efficacy of a supraciliary micro-stent (CyPass Micro-Stent; Transcend Medical, Menlo Park, California, USA) for surgical treatment of glaucoma in patients refractory to topical medications. DESIGN Multicenter, single-arm interventional study. METHODS Patients with open-angle glaucoma (Shaffer Grade 3 and 4) and(More)
AbstractPurposeTo compare prospectively the results of deep sclerectomy (DS) vs deep sclerectomy with collagen implant (DSCI)MethodsRandomized prospective trial involving 26 eyes (13 patients) with medically uncontrolled primary and secondary open angle glaucoma. Collagen implant was randomly assigned to one eye of each patient.Results:The mean follow-up(More)
